Where can I find Emissions Legal Headers for third gen?

Im installing the LT1 in the car and am wanting to buy headers. But I want to go with LT's. Is there a header that I can go with? Or is it possible to use the Hooker Super Comp LT's and still pass emissions. If not, which headers can I go with? Im looking at the SLP headers, will these work nicely? How do they usually compare to other headers.

I have SLP headers. They work out perfect. 50 State legal. They run about $500 to $550 at most places.

if your new headers have air tubes and o2 sensor bungs on them then they will be emmision legal and it wont effect emissions one bit,regardles of brand,unless maybe say the bung is in the wrong spot and it screws up o2 sensor.emmission legal one thing.swapaibilty another.your major names should give you trouble free fit

The Edelbrock TES would be a good choice. Not 100% sure if they bolt up to LT1 heads or not.

There are no long tube headers that are 50-state legal. SLP 1 3/4" headers would be my choice for LT1 engines, but I would get a 2.5" y-pipe made up custom for it, instead of using the 2.25" y-pipe they come with.

Edelbrock headers are at the bottom of my list, stay away from them. Do a search on this forum and the exhaust forum at http://www.thirdgen.org/ where I moderate, you will see why I dont like them.
